How to set Timer for ir ganerate

Tool/software: TI C/C++ Compiler

void inittimerIR(void)
{
  //  CLKCONCMD &= ~0x38;;
  //  CLKCONCMD |= 0x18;
 
  //Inittimer1();
  //Inittimer3();
  T1CTL = 0x00;
  T1CCTL0 = 0x10 | 0x04;
  T1CCTL1 = 0x18 | 0x04;
 
  //T1CNTL = 0;
  //  T1CC0 = 85;
  //  T1CC1=21;
  T1CC0L = 2;
  T1CC0H = 0;
  T1CC1L = 1;
  T1CC1H = 0;
 
  T1CNTL = 0;
  T1CTL = 0x00 | 0x02;
 
  // Wait till the single bit is cleared
  while (T1CNTL == 0);
 
  // Stop timer 1
  //T1CTL = 0x00;
 
  //timer3
  //T3CTL = 0x04;
  T3CTL = 0x40 | 0x02;   // 4
  T3CCTL0 = 0x10 | 0x04;
  T3CCTL1 = 0x18 | 0x04;
 
  //  T3CC0 = 0xD2;    //211
  //  T3CC1 = 0x46;    //105
  T3CC0 = 0xD2;    // 
  T3CC1 = 0x46;    // 
  
  //IRCTL |= 1;
}

void SendIRsignal(void)
{
  IRCTL |= 1;
  writeI2C(IRdata,IRdataLen);
  IRCTL |= 0;
}

Unfortunately, we compiler experts lack the knowledge to help you with this particular question.  What device are you using?  Once I know that, I will move this thread to the relevant device forum.

Thanks and regards,

I use zstack and cc2530.

You can try to refer to RemoTI IR Signal Generation Application Note.
